Menu items dosen’t show right

Hi

I installed the Bellows accordion menu and everything looked OK. But when I clicked on the menu items and the subpages not all pages was displayed right. Some subpages had the entire text content of the page displayed and not only the page title as they are supposed to. I put the plugin live on my category templet page so you can see: https://passionforhalsa.se/category/blogg
Another thing is that you can not name the menu? If this plugin will work, I will go pro, but I need to know that it is actually working first.

The page I need help with: [log in to see the link]
